Probabilistic seismic hazard analysis (PSHA) combines the probabilities of all earthquake scenarios with different magnitudes and distances with predictions of resulting ground motion intensity, in order to compute seismic hazard at a site. PSHA also incorporates uncertainties in ground motion predictions, by considering multiple Ground Motion Prediction ("attenuation") Models (GMPMs). Current ...
[1] ElarmS is a network-based methodology for rapid earthquake detection, location and hazard assessment in the form of magnitude estimation and peak ground motion prediction. The methodology is currently being tested as part of the real-time seismic system in California leveraging the resources of the California Integrated Seismic Network (CISN) and the Advanced National Seismic System. A tota...
Australia is in a unique position globally being a continent where Mw7.0 events can occur in the Craton, and potentially similar large events in the non-Craton areas, however only a recorded history of around 150-200 years or less exists in most locations. Although a lowmoderate seismicity country, many locations have already experienced damaging earthquakes. The recent earthquake hazard maps i...
Probabilistic seismic hazard maps are widely used for engineering design, land use planning, and disaster mitigation etc. This study conducted a review of readily available information on tectonic setting, geology, and seismicity, and the attenuation of peak ground acceleration (PGA) of Taiwan for completing the revised probabilistic seismic hazard maps by the state-of-the-art probabilistic sei...
There is a growing interest in the development of procedures for the design of structures exposed to multiple hazards. The goal is to achieve safer and/or more economical designs than would be the case if the structures were analyzed independently for each hazard and an envelope of the demands induced by each of the hazards were used for member sizing. We describe an optimization approach to mu...
Like all theories in any branch of physics, theories of the seismic source should be testable (i.e., they should be formulated so that they can be objectively compared to observations and rejected if they disagree). Unfortunately, many widely held theories of the seismic source, such as the elastic rebound paradigm and characteristic earthquake model, and theories for applying them to make prob...
